MATLAB: Coordinates of nodes in plot graph

graphplot

Hi,

after displaying a graph with the "Force Directed" algorithm by calling

plot(graph(G), 'force')

I would like to get the coordinates of the nodes of the displayed graph. Is there a way to extract them or to only call the "Force Directed" algorithm to get those?

Best Regards

Copying my answer from this Answers post:

B = graph(bucky);
h = plot(B);
X = h.XData;
Y = h.YData;
fprintf("Node 1 is located at (%f, %f)\n", X(1), Y(1))
Node 1 is located at (0.103347, -1.803899)
% Turn on the axes ticks so you can check the coordinates
ax = ancestor(h, 'axes');
ax.XTickMode = 'auto';
ax.YTickMode = 'auto';
xticks(-5:5)
% Draw lines -- X marks the spot
xline(X(1), 'r')
yline(Y(1), 'r')

You can use highlight to set that marker to 'none'. The GraphPlot object h contains all the graphical properties of the plotted graph, so it's not possible to find a specific marker as a seperate object - all changes have to be made by changing the properties of the GraphPlot object h.

MATLAB: Plot graphs at conclusion of a ‘for loop’

For my purposes here (and since you didn’t post it), I’m using ‘k’ as the loop index. So assume this loop:

for k = ...
    % LogPriceReturn Graph
    x1(k) = Timestep; % sets x axis equal to the 'Timestep'

    y1(k) = LogPriceReturn; % sets y axis equal to the 'LogPriceReturn'
    x2(k) = Timestep; % sets x axis equal to the 'Timestep'
    y2(k) = StockPrice; % sets y axis equal to the 'StockPrice'
end
      figure(1); % opens a new figure for graph

      plot(x1,y1, 'Marker','o', 'MarkerFaceColor','black'); hold on % plots graph of x and y, using 'hold on' command to retain each loop result

      title('Log Price Return'); % sets the title of graph

      xlabel('Timestep'); % sets x-axis label of graph

      ylabel('Log Price Return Graph'); % sets y-axis label of graph

      axis([1 n -1 1]); % formats axis limits

      % StockPrice Graph
      figure(2) % opens a new figure for graph
      plot(x2,y2, 'Marker','o', 'MarkerFaceColor', 'black'); hold on % plots graph of x and y, using 'hold on' command to retain each loop result
      title('Stock Price'); % sets the title of graph
      xlabel('Timestep'); % sets x-axis label of graph
      ylabel('Stock Price'); % sets y-axis label of graph
      axis([1 n -inf inf]); % formats axis limits

NOTE — This is UNTESTED CODE. It should work, but may require minor modification.
